Timo Iden, Jan Höcker
Inadvertent perioperative hypothermia (body core temperature < 36 °C) is a serious complication leading to increased rates of wound infection, higher blood loss associated with increased transfusion requirements as well as patient dissatisfaction among others. Body core temperature is a vital parameter and needs constant monitoring just like heart rate, blood pressure and arterial oxygen saturation. Patient-, anesthesia-, surgery- and environment-related risk factors were identified for occurring perioperative hypothermia...

An insidious increase in the incidence of obesity, insulin resistance, and hyperlipidemia has led to an epidemic of type 2 diabetes worldwide. Tinospora crispa (T. crispa) is a familiar plant traditionally used in herbal medicine for diabetes; however, the major active ingredients of this plant are still unclear. In this study, we identified the therapeutic effects of borapetoside E, a small molecule extracted from T. crispa, in high-fat-diet (HFD)-induced obesity in mice. The therapeutic effects of borapetoside E in HFD-induced obese mice were assessed physiologically, histologically, and biochemically following intraperitoneal injection...

Pulmonary hypertension due to lung diseases In 2015 the European Society of Cardiology and European Respiratory Society published new guidelines on the diagnosis and treatment of pulmonary hypertension (PH). PH due to lung diseases and/or hypoxia was classified as a separate entity. PH is common in lung diseases, but seldom severe. Nevertheless, the presence of PH in a patient with lung disease is associated with worse outcome. If there is clinical suspicion of PH in a patient with lung disease, echocardiography is recommended, and if there are signs of severe PH and/or severe right ventricular dysfunction the patient should be referred to a PH expert centre...

Lonidamine, an anticancer drug that acts on mitochondria, has poor water solubility. Mitochondria are the primary source of cellular reactive oxygen species (ROS), which are necessary for photodynamic therapy. Hence, a mitochondria-targeting drug delivery system loaded with Lonidamine and a ROS-produced photosensitizer could improve the bioavailability of Lonidamine and maximize photodynamic therapeutic efficiency. Here we report, for the first time, new IR-780 and Lonidamine encapsulated mitochondria-targeting thermosensitive liposomes (IL-TTSL)...

Near infrared (NIR) triggered cyanine dyes have attracted considerable attentions in multi-modal tumor theranostics. However, near infrared (NIR) cyanine dyes used in tumor treatment often suffer from low fluorescence intensity and weak singlet oxygen generation efficiency, resulting in inadequate diagnostic and therapy efficacies for tumors. It is still a great challenge to improve both the photodynamic therapy (PDT) and fluorescent imaging (FLI) efficacy of cyanine dyes in tumor applications. Herein, a novel multifunctional nanoagent of AuNRs@SiO2-IR795 was developed to realize the integrated photothermal/photodynamic therapy (PTT/PDT) and FLI at a very low dosage of IR795 (0...

Luana Schito, Gregg L Semenza
Intratumoral hypoxia (reduced O2 availability) is a common finding in human cancer and leads to increased activity of hypoxia-inducible factors (HIFs), which regulate the expression of genes that contribute to angiogenesis, metabolic reprogramming, extracellular matrix remodeling, epithelial-mesenchymal transition, motility, invasion, metastasis, cancer stem cell maintenance, immune evasion, and resistance to chemotherapy and radiation therapy. Conventional anticancer therapies target well-oxygenated and proliferating cancer cells, whereas there are no approved therapies that target hypoxic cancer cells, despite growing clinical and experimental evidence indicating that intratumoral hypoxia is a critical microenvironmental factor driving cancer progression...

AIMS: Evofosfamide (TH-302) is a hypoxia-activated prodrug (HAP) which releases the DNA damaging bromo-isophosphoramide (Br-IPM) moiety selectively under hypoxic conditions. Since solid tumors are known to have hypoxic regions, HAPs in combination with chemotherapy or radiotherapy will be beneficial. We tested the oxygen dependence of the release kinetics of Br-IPM using Electron Paramagnetic Resonance (EPR) with spin trapping by monitoring the redox-cycling the nitroimidazole moiety of TH-302 and oxygen dependence of TH-302 on in vitro cytotoxicity at different levels of hypoxia was also examined...

Botulinum toxin is now used for numerous indications including dystonias, spasticity, cerebral palsy, hyperhidrosis, cosmetics and chronic migraine. It has to be injected into its target tissues thus causing injection site pain. We wanted to compare the efficacy of various analgesic interventions suggested for reduction of injection site pain. In 13 healthy controls, pain thresholds in the fingertips II and III bilaterally were determined by the Mechanical Pain Threshold Test and the Repetitive Pain Stimulation Test at baseline and under nitrous oxide/oxygen, ice spray, local anaesthetic cream and forearm ischaemia...

Approximately 20% of human cancers is attributable to DNA oncogenic viruses such as human papillomavirus (HPV), hepatitis B virus (HBV), and Epstein-Barr virus (EBV). Unrepaired DNA damage is the most common and overlapping feature of these DNA oncogenic viruses and a source of genomic instability and tumour development. Sustained DNA damage results from unceasing production of reactive oxygen species and activation of inflammasome cascades that trigger genomic changes and increased propensity of epigenetic alterations...

Pathological angiogenesis in the eye is an important feature in the pathophysiology of many vision-threatening diseases, including retinopathy of prematurity, diabetic retinopathy, and age-related macular degeneration, as well as corneal diseases with abnormal angiogenesis. Development of reproducible and reliable animal models of ocular angiogenesis has advanced our understanding of both the normal development and the pathobiology of ocular neovascularization. These models have also proven to be valuable experimental tools with which to easily evaluate potential antiangiogenic therapies beyond eye research...

Throughout the world both intentional and inadvertent exposure to carbon monoxide (CO) remains an important public health issue. While CO poisoning can be lethal, the morbidity is predominantly due to nervous system injury. A previously healthy 22-year-old woman was found unconscious at home by her sister. Her parents were found dead in the house with a recent history of a dysfunctional furnace. She was presumed to have CO poisoning despite an initial carboxyhaemoglobin level of 2.5%. Patient had both clinical and radiological evidence of neurological damage...

Near infrared (NIR) light triggered phototherapy including photothermal therapy (PTT) and photodynamic therapy (PDT) affords superior outcome in cancer treatment. However, the reactive oxygen species (ROS) generated by NIR-excited upconversion nanostructure is limited by the feeble upconverted light which cannot activate PDT agents efficiently. Here, an IR-808 dye sensitized upconversion nanoparticle (UCNP) with a chlorin e6 (Ce6)-functionalized silica layer is developed for PDT agent. The two booster effectors (dye-sensitization and core-shell enhancement) synergistically amplify the upconversion efficiency, therefore achieving superbright visible emission under low 808 nm light excitation...

Although oral drug delivery is the most common route of drug administration, the conventional polymeric nanocarriers exhibit a low drug loading capacity and low stability in the gastrointestinal (GI) environments. In this study, a newly designed silica-containing redox nanoparticle (siRNP) with reactive oxygen species (ROS) scavenging capacity is developed as an ideal oral nanocarrier for a novel hydrophobic anticancer compound BNS-22 to treat colitis-associated colon cancer in vivo. Crosslinking of silica moieties significantly enhances the stability under acidic conditions and improves BNS-22 loading capacity of siRNP compared to the conventional redox nanoparticle...

We prepare for the first time a novel type of fluorescent carbon quantum dot (or carbon dot, CD) with intrinsic mitochondrial targeting ability by a one-step hydrothermal treatment of chitosan, ethylenediamine and mercaptosuccinic acid. The as-prepared CDs can realize mitochondrial imaging and mitochondria-targeted photodynamic cancer therapy without further modifications of other mitochondriotropic ligands (such as triphenylphosphine, TPP). Currently, many commercial mitochondrial probes suffer from the lack of modifiable groups, poor photostability, short tracking time, high cost and/or complicated staining procedures, which severely limit their applications in live-cell mitochondrial imaging...
